What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

The monitoring part of the equipment detection point is the transmission assembly


Combining equipment for point inspection and regular repair, carry out simple diagnosis of main production equipment, equipment on-line monitoring and management of key equipment status maintenance, tendency to manage fault degradation curve drawing of mine crushing equipment status management, comprehensive diagnosis of rotating equipment faults, fault diagnosis of cone crushers, Predict the failure cycle of mining equipment, analyze failure modes, and grasp the probability of failure. Early detection of potential equipment failures, making maintenance decisions, and realizing predictive maintenance of equipment. In recent years, the failure rate has increased, and common failures and sudden failures have increased year by year with the growth of service life. The overhaul is difficult, the overhaul cost is high, and the equipment operation performance is declining year by year. Analysis of the current situation of the moving cone bevel gear cone crusher The type cone crusher is the main production equipment of Lingxiang Iron Mine. Failure mode: The horizontal shaft sleeve is glued, the transmission and the large and small bevel gears are worn and the teeth are broken, the gap between the large copper sleeve of the main shaft is increased, the spherical bush is strained, and the internal failure of the motor. Cone crusher fault diagnosis model analysis fault diagnosis program must be type cone crusher fault diagnosis program is established as shown in the figure, the establishment of the diagnosis part of the fault diagnosis steps, take the cone crusher as an example for diagnosis. The equipment detection point is shown in the figure. The monitoring part is the transmission assembly, and the measurement parameter is the vibration speed. Equipment online monitoring, diagnosis and analysis year and month. The results of the analysis of the cone crusher online monitoring data are listed in the table. The equipment failure fluctuation situation and law, the four monitored data all fluctuate, and the water pressure fluctuation range is large, indicating that the equipment failure is not Independent existence is the interconnection of the internal structure of the host. The results of the frequency spectrum analysis of the vibration velocity of the measuring points of the three equipment No. The equipment No. three side intestines are shown in the figure as the state of the crusher. The internal failure of the host is a complicated factor.

Therefore, the number of measuring points has been intensively monitored, and the frequency spectrum has been used for precise testing and analysis.
